Traffic Message Channel Module (TMC) (2006-2007): Design: Antenna
On the S40 a combined AM/FM (main and sub) and TMC-antenna is used. The antenna is integrated in the rear windshield.
There is a combined AM/FM main antenna integrated in the right door window. There is also an antenna for FMsub, which s a combined FMsub/TMC antenna integrated in the rear window.
On the C70 there are two antennas. A combined AM/FM rod antenna, which is integrated on the rear right-hand side. An FMsub antenna, which is a combined FMsub/TMC antenna and is behind the bumper.
The frequency range of the antenna is 87.5 - 108.0 MHz.
The signals from the antenna are amplified or adjusted by an antenna amplifier.
The antenna amplifier transmits TMC/FM sub-signals on to the Traffic message channel module (TMC). The FM sub-signals are then transmitted to the AM/FM tuner module (AFM) (applies to vehicles with structure week up to and including 200445) or Integrated Audio Module (IAM) (applies to vehicles with structure week from and including 200446).
